我正在尝试使用 Python 3.8 连接到 Heroku Redis，以节省 Redis 字典和字符串。我正在尝试使用 Herokus Redis 作为 Telegram 机器人的持久性（库：python-telegram-bot 和 Telethon） 在 SET() 上调用 Redis 实例时，我收到以下错误：

我想知道错误是在连接到 Redis 时引起的（我只启动了一次连接，Heroku 可能正在更改 REDIS_URL）还是在尝试传入字典时...
这是 redis_connector 初始化器：
redis_connector = redis.Redis(host=secrets.get_var('REDIS_URL'), port=14909, db=0, decode_responses=False)
这是导致错误的代码行：
redis_connector.hmset('persistence:{}{}{}'.format(self.method, self.user_id, self.chat_id), obj_dict)
这是我试图通过的字典：
{'method': 'account', 'chat_id': 1234, 'user_id': 1234, 'message_id': 55, 'phone': -1, 'password': -1, 'code': -1, 'phone_code_hash': -1, 'code_tries': 0}
完整代码参考： https : //github.com/davidwickerhf/karim（特别是https://github.com/davidwickerhf/karim/blob/main/karim/classes/persistence.py，https://github.com /davidwickerhf/karim/blob/main/karim/classes/session_manager.py和https://github.com/davidwickerhf/karim/blob/main/karim/__init__.py - 文件被称为 redis 连接）
提前谢谢你的帮助
